IMPROVEMENT IN DEVICES FOR DRILLING RAILS.

Specification forming part of Letters Patent No. 161 ,4 [8, dated March30, 1875; application filed December 22, 1874.

To all whom it may concern:

Be it known that I, JOHN H. LAKEY, of Turner Junction, in the county ofDu Page and State of Illinois, have invented new and useful Improvementsin Drills, of which the following is a full description, reference beinghad to the accompanying drawings, in which Figure 1 is a side elevationand Fig. 2 a vertical section.

The chief object of this invention is to construct a drill which can bereadily attached to the top of an ordinary T-rail, and be used formending broken rails on the track.

Heretofore drills have been used for this purpose so constructed thatthey can be secured to the under side of the rail, which cannot be doneexcept between the ties, and then the ground must be dug away under therail, which it is not always easy to do.

Another object is to simplify the construcrion of the drill, which I doby so making it that the drill proper is advanced by an independentscrew instead of by the movement of the drill-head and operating-lever.

In the drawings, A represents the frame which carries the operativeparts of the drill. It has two jaws, a b, the inside of one ofwhichconforms to the shape of the head of the rail upon which the frameis to be placed. The other is adapted to receive the key 0, which may beused to hold the frame in place upon the head of therail. This frame maybe made either of wrought or cast metal, and should be two inches ormore in width on the top. B is the drill-stock, which passes through andcan be revolved in the part c of the frame. O is the handle or lever foroperating the drill. It is provided with a ratchet, f, and is to besecured to the drill-stock B by means of a collar, g, or in some otherknown manner. In the drill-stock B is a deep socket which receives thedrill d. h is a screw which passes through the head or outer end of thedrill-stock, and by the use of which the drill d is advanced. The headof this screw may be provided with arms or with holes *5 to receive oneor more re movable arms. The jaws a b are stationary.

It is customary to mend broken rails on the track by drilling holesthrough the neck and applying a fish-joint. This work can be greatlyfacilitated by the use of my device.

.In use the frame A is secured to the top of the rail, most convenientlyby a key, 0. The drill 01 does not advance simply by the movement of thelever O, as is usual, but the operator holds the screw h by means of oneof the arms, so as to prevent it from turning with the movement of thedrill-stock B, but the drillstock will turn on k, carrying it forwardand forcing the drill forward. To do this, however, if the movement ofthe lever 0, when operating the drill-stock, be right-handed, the screwh must be left-handed. This mode of advancing the drill enables me tomake a cheaper device for the purpose than those now in use, but equallyefficient. The parts may be made of any suitable metal.

The drill-stock can be driven by the use of gear-wheels, its movementbeing continuous instead of intermittent, as when the ratchet is used;hence I do not confine myself to the ratchet, though it is cheaper andless cumbersome than gearing.

The distinguishing feature of this part of my invention is in theconstruction of the parts, so that the drill is advanced by theindependent screw h instead of with the drill-stock, as usual.

What I claim as new, and desire to secure by Letters Patent, is asfollows:

The combination, as described and shown, of the frame A, key 0,drill-stock B, and actuating lever or handle 0 with the sliding drill dand screw h acting directly against the head of the drill, substantiallyas specified.
